Question about 2002 Audi A4
Possible problem with the voltage regulator. Call an Audi dealer and ask if that's a separate part or if it's built into the alternator. If it's separate, you could replace just the regulator. If not, you'd have to get the alternator.
Another outside chance is that the load reduction relay in the car is getting screwy, and that may need replacement.
